SPECIFICATION forming part of Letters Patent No. 290,560, dated December18, 1883.

Application filed September 24, 1883. (No model.)

To col; whom, it may concern.-

Be it known that we, GILFORD FLEWWEL- LING and GILBERT J. Hnnnrs, ofHampton, Kings county, New Brunswick, Dominion of Canada, have inventeda new and Improved Match-Sawing Machine, of which the following is afull, clear, and exact description.

Our invention consists of improvements in the arrangement of apparatusfor holding and shifting the blocks to be sawed, and also for presentingthem to the saws, in a machine in which the blocks are carried onslowly-revolving horizontal tables or disks to the grooving or pointingsaws, also to the slitting-saws, and also to the cutting-off saws,whereby it is designed to improve the efficiencyof such machines, all ashereinafter fully described.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of our improved machine, with a part inhorizontal section, and with one of the slitting-saws removed from thedisk which carries said saws. Fig. 2 is a detail of one of theblock-carrying disks and one of the carriages for the blocks to besawed, in section. Fig. 8 is a plan of Fig. 2. Fig. at is a plan view ofa gage and holder that is em ployed to regulate the setting of theblocks to the saws. Fig. 5 is a longitudinal sectional elevation of thegage and holder represented in Fig. 4, and Fig. 6 is alongitudinalsectional elevation of the machine on the line as x of- Fig. 1.

The machine consists, essentially, of the two block-carrying disks a,with a disk, b, between them, carrying a series of slitting-saws, c,together with grooving and pointing saws d, and cutting-cit saws 6,arranged as shown in Figs. 1 and 2 of the drawings, and provided withsuitable driving-gear, as hereinafter described,

whereby the blocks, f, tobe sawed into matchcards may be placed oncarriages g, and secured in radial grooves h, to be presented to thesaws, first to be trimmed, next to be pointed, then slitted, and finallycut off, the blocks being shifted forward each time the cards are cutoff until the blocks are finished. \Ve now propose for a better means ofholding the blocks, and also to enable larger blocks of the carriage,and the sliding wedge j being placed alongside of the clamp and gearedby a cog-rack, m, on its upper edge with a leverpinion, a, pivoted tothe clamp at 0, so that the operator may readily shift the lever-in onedirection by one hand to release the block, shift the blocks to resetthem by the other hand, and reversethe lever to secure the blocks again.hen the blocks f are put in the carriages, they are at first to be setso as only to project sufficiently to be trimmed off at the ends by thesaws e, and for gaging them for being so trimmed, and also for beingafterward set forward the length of the slitted cards to be cut ofi, wehave provided a gage, consisting of the arm 12, swinging around thevertical pivot qof the disk a, and having a vertical gage-stop, 3,against which the blocks are to be set for sawing off the cards, andthere is ahorizontally-projecting stop, 15, attached to stop 8, againstwhich the ends of the blocks are to be set for trimming them to beginwith. This latter stop if is in practice to be pivoted to the verticalstop 8 at a, and a light spring will be employed to lift it up in therange of the blocks when the said stop is to be used, which spring willallow of the said stop i being pressed down out of the way when it isnot to be used. This gage is to be located where the operator stands inadvance of the saws c, as represented at the right hand of Fig. 1, andit has a handle, '0, by which to swing it to and from the position ofthe carriages or blocks. Said gage also has anotched holding-latch, w,pivoted to it in a suitable position under the table for engaging a pin,is, projecting down through a slot, '1, in the table from the carriageg, to hold the table against v sliding forward and backward in the ways71 when the clamp i is released and the blocks are being shifted. Whenthe blocks f pass the saws e to be trimmed or cut off, the pins an ofthe carriages run along a cam-groove, z, in any stationary plate belowthe table, which groove is suitably inclined in the first part, a,traversed by the pin to draw the carriage in- ICO ward, and theseeondpart, b, is inclined to shift the carriage outward with relationto thetable, so that the blocks pass the saw in a straight line, to be cutstraight across, rather than in a curved line, as they would be out ifthey followed the curve of the tables motion.

The tables a are mounted by their pivots or spindles q in sockets 0,supported on the frametimbers d, and we now propose to gear them withthe shaft 6, which carries the saw-disk b, by belts f from a pulley, g,on said shaft, vertieal shafts h, and the worm-shafts 1;, saidworm-shafts gearing with the shafts h by suitable bevel-wheels, and alsogearing with the disks a by the toothed rims j, said worm-gears beingnow employed in preference to the frietion-gears heretofore employed fordriving these tables. The cutting-off saws e are to be driven by beltsfrom any suitable driving-pulleys, and running on the small pulleys k ontheir arbors, which are mounted in suitable bearings, m, on anextension, at, of the frame, andwe propose to apply other and smallerout ting-off saws, Z, to the outer ends of these arbors for trimming orcutting in two the last double bunches of cards which are taken from thecarriages by the attendant and trimmed) by these saws.

The grooving-saws d are mounted on vertical arbors p, and are drivenfrom the large drum g on shaft 0 by belts 8. Power is applied to shaft 0by the main driving-belt t and pulley a; The worm-shafts t" are to beshifted out of gear with the toothed rims j, when required, by slidingboxes 1) and rods 10. Having thus described our invention, we claim asnew and desire to secure by Letters Patent 1. In a match-sawing machine,the combination,with the carriage 9, having the flanges k, of thesliding wedge j, e1amping-p1ate i, and the lever-pinion a, saidlever-pinion being pivoted to the clamping-plate and gearing with 2. Ina matchsawing machine, carriages having clamps to hold the blocks, andarranged to slide in the ways h of the tables a, and also having astud-pin, w, projecting through the tables a, in combination with agrooved cam or guide, .2, whereby the blocks are made to move in astraight line along the saws 6 while being carried on the revolvingtables, substantially as described.

3. In a match-sawing machine, the combination, with the table a and thesliding carriages 7, having clamps for holding the blocks of wood, ofthe swinging arm 10, provided with the stop-gages s t on its free end,substantially as herein shown and described.

4. In a match-sawing machine, stop-gages s and t, in combination withthe carriages 9, having clamps to hold the wood blocks, and beingarranged in radial grooves h in the tables a, said stop-gages beingarranged on the arm 1), fitted to swing around the pivots q of thetables, substantially as described.

5. In a match-sawing machine,vertical stop gage s and horizontalstop-gage t, in combination with, thecarriages g, having clamps toholffihe wood blocks, and being arranged to shift along the radialgrooves 71. of the tables a, said gages being mounted on the swingingarm 2, and the gage 2%, attached to gage s, and being pivoted thereto tobe set in or out of range of the blocks, substantially as described.

6. In a match-sawing machine; the combination, with the slotted table aand the sliding carriage 9, provided with pin y, of the swinging arm 1),having a stop-latch, 10, engaging the pin of the carriage, substantiallyas herein shown and described.
